Release time: 2019-07-10


  To help customers better understand zirconia oxygen analyzers, Tianfen Instruments has summarized some professional knowledge about zirconia oxygen analyzers in a Q&A format. Let's follow the footsteps of the technicians from Anhui Tianfen Instruments Co., Ltd. to learn more!

  What are the components of a zirconia oxygen analyzer?

  Answer: A zirconia analyzer consists of a detector and a converter.

  What is the main function of a zirconia analyzer?

  Answer: It is used in gas combustion management and control to measure the oxygen concentration in combustion exhaust.

  What is the working principle of a zirconia oxygen analyzer?

  Answer: It mainly consists of a zirconia solid electrolyte that can conduct oxygen ions at high temperatures. On one side of the sensor is the gas to be measured, and on the other side is the reference air. Due to the different oxygen concentrations on both sides, an oxygen battery is formed, and by measuring the electromotive force of the battery, the oxygen concentration can be accurately determined.

  What are the measurement methods of a zirconia oxygen analyzer?

  Answer: One is the direct insertion type, and the other is the pump extraction type. For the direct insertion type, the insertion depth needs to be known (Tianfen Instruments has a smaller flange DN50).

  Where is a zirconia analyzer generally used?

  Answer: It is generally used in boilers, kilns, heating furnaces, and other combustion equipment to measure the oxygen content in flue gas produced during combustion in real time. Many people use it, and it's used in many industries.

  Can a zirconia sensor be connected to a general microcontroller?

  Answer: No.

  Is a conventional zirconia analyzer just a wall-mounted converter host?

  Answer: Yes, the transmitter has a 4-20mA current output to the DCS system.

  What product parameters generally need to be known before inquiring about the price of a zirconia analyzer?

  Answer: Before determining the product price, we need to know the flue gas temperature, boiler fuel type, flange specifications, insertion depth, etc., to provide a final quotation. The measurement range of the zirconia oxygen analyzer produced by Anhui Tianfen Instruments Co., Ltd. is 0-25%.

EXNFZRO®2 Explosion-proof Zirconia Oxygen Analyzer Significance of Measuring Oxygen Content with Zirconia Analyzer Flue gas oxygen content is one of the important monitoring parameters for boiler operation and an important basis for reflecting the completeness of combustion equipment and boiler operation. Its value is related to factors such as boiler structure, type and nature of fuel, boiler load, operating air supply conditions, and equipment sealing conditions. The smaller the oxygen content, i.e., the smaller the excess air coefficient, the more it indicates increased heat loss due to incomplete chemical combustion and mechanical incomplete combustion; the larger the oxygen content, i.e., the larger the excess air coefficient, the more it indicates excessive air supply. Excess air causes a drop in furnace temperature, which not only affects combustion but also carries away a large amount of heat and dust, increasing the calculated concentration of pollutant emissions. At the same time, a large air volume also increases the power consumption of flue gas exhaust. Controlling flue gas oxygen content is very important for controlling the combustion process and achieving safe, efficient, and low-pollution emissions. Application Scope The zirconia oxygen analyzer is an instrument used to monitor and control the oxygen concentration in combustion gases, boilers, and industrial furnaces. It is widely used in coal-fired power plants, gas boilers, waste incineration boilers, hazardous waste disposal incinerators, petrochemical cracking furnaces, metallurgical industry blast furnace hot blast stoves, oxygen-enriched combustion air pipelines, sintering furnaces, heating furnaces, heat treatment furnaces, metal material annealing furnaces, air separation oxygen production, food industry, cement kilns in the building materials industry, glass kilns, inert gas protection furnaces in the semiconductor industry, electrode material production furnaces in the lithium battery industry, and waste lithium battery recycling. It helps save energy and can also reduce CO2, SOX, and NOx emissions by controlling complete combustion, contributing to environmental protection, preventing global warming, and reducing air pollution.
